Manufacturing
Where is Tesla Optimus built?
What Tesla has said about where Optimus will be made, Fremont first and Giga Texas later, and why the factory is a stated plan on the record rather than a confirmed, running line.
Tesla says the first Optimus production lines are going in at its Fremont factory in California, with a larger dedicated plant under construction at Giga Texas in Austin. No running line is verified yet. There is no Optimus factory confirmed as operating at volume on the verified record, which still puts the program at research stage. What Tesla and public sources describe is a plan with two sites. First, Fremont: Tesla decommissioned its Model S and X assembly lines and is installing the initial Optimus production line on that floor, and the City of Fremont publicly named the Fremont factory as the chosen site for Optimus manufacturing. Second, Giga Texas: Tesla is building a second, much larger Optimus factory in Austin for later mass production, targeted around 2027. So the honest answer is that Fremont is the stated starting point and Giga Texas the stated scale-up, but both are Tesla's forward plan, and neither is a verified, running humanoid line today. If and when a line is confirmed producing units, the record moves from plan to fact. This is general information, not investment advice.
People ask where Optimus is built as if a factory is already humming, and the honest picture is a plan more than a running line. The verified record puts Optimus at research stage, with no confirmed volume production. What Tesla describes is a two-site strategy: it cleared the Model S and X assembly at its Fremont factory in California to install the first Optimus line, a move the City of Fremont publicly confirmed as choosing Fremont for Optimus manufacturing, and it is building a second, larger Optimus plant at Giga Texas in Austin for later mass production.
That larger site is the one tied to Tesla's big long-term unit ambitions. Both are Tesla's stated plan, so we mark them claimed, not a verified operating factory. For the closely linked question of when production actually starts, the same slippage caveats apply.

What actually exists today
| What people ask about | Status | The reality |
|---|---|---|
| A verified operating factory | Not confirmed | No Optimus factory is confirmed operating at volume on the record; the program is at research stage. Tesla says lines are being installed, which is not the same as a verified running line. |
| The first site | Fremont, California | Tesla decommissioned its Fremont Model S and X assembly and is installing the initial Optimus line there. The City of Fremont publicly named the Fremont factory as the chosen Optimus manufacturing site. |
| The scale-up site | Giga Texas, Austin | Tesla is building a second, larger Optimus factory at Giga Texas for later mass production, tied to its long-term unit ambitions and targeted around 2027. It is a plan on the record, not an operating line. |
| Production outside the US | No plan disclosed | Tesla has disclosed no plan to build Optimus outside the United States. Both stated sites are domestic. Absence here reflects no disclosure, not a confirmed US-only policy. |
How to read the factory question
Where a thing will be built and where it is being built are different claims. Hold the two apart, and weigh the concrete signal against the unconfirmed status.
Fremont is physically being converted
Clearing the Model S and X lines and installing Optimus tooling is a real, expensive step, and a municipal source confirms Fremont as the chosen site. This is more than a slide; the floor is changing.
Installing a line is not running one
A converted floor is not a verified operating factory. Until units are confirmed coming off a line, the honest status is a site being prepared, not a plant in production.
Giga Texas is the real volume bet
The big unit ambitions attach to the larger Texas plant, which is under construction for later years. Its scale is a plan, and plans at this size have moved before.
Claimed, and watched
We treat both sites as Tesla's stated plan and update the moment the record confirms a running line. Until then, no operating Optimus factory is verified.

What would change this
We track the program against the verified registry record, so you do not have to. Any one of these moves the verdict, and each becomes a dated line the week it happens:
- The record confirms a running Optimus line at Fremont or Giga Texas, with a verified unit count.
- Tesla names a new or additional Optimus production site.
- Tesla discloses a production location outside the United States.
- Scrutiny of the program tends to sharpen after real incidents. Right now the verified record holds zero safety incidents for the Tesla Optimus, and every new one is logged the week it lands.
How we know this
The verified spine is the registry Optimus record: research stage, no confirmed volume line. The Fremont and Giga Texas sites are Tesla's own statements plus a City of Fremont announcement, dated and attributed and labeled claimed rather than a verified operating factory. We present no running line the record has not confirmed.
If the record confirms a running Optimus factory or a new site, or you can show us we got something wrong, our corrections process logs the response on the record.
Common questions
Where is Tesla Optimus built?
Tesla says the first Optimus production lines are being installed at its Fremont factory in California, on the floor cleared by decommissioning its Model S and X assembly, and a City of Fremont announcement names Fremont as the chosen Optimus manufacturing site. A second, larger Optimus factory is under construction at Giga Texas in Austin for later mass production.
No Optimus factory is verified operating at volume yet; both sites are Tesla's stated plan. This is general information, not investment advice.
Is Tesla actually making Optimus robots at Fremont now?
Tesla has cleared its Model S and X lines and says it is installing the first Optimus line at Fremont, which is a concrete conversion step. But installing a line is not the same as running one, and the verified record does not yet confirm units coming off a line. The honest status is a site being prepared, not a plant confirmed in production.
What is being built at Giga Texas?
Is Tesla Optimus built outside the United States?
Tesla has disclosed no plan to manufacture Optimus outside the United States; both stated sites, Fremont and Giga Texas, are domestic. That is an absence of disclosure rather than a confirmed US-only policy, and it would change the day Tesla names an international site.
